Thanks very much for the offer, however, I have been so busy with my 
daughter I have not had much time for anything else.

Nothing happened!! Even with volume all the way up in System 
Preferences on Output.  I am beginning to think I may have had it 
misswired.  but it did TX after pushing the TRANSMIT button the PRO

I checked the wiring in the SL-1 and it all worked with the  PRO III 
with the Orion I and with the  PROIII before I sold the G5 mac 
computer.

I wouldn't trigger PPT.

This may be true, but it is now off to its Maker.

Neat idea, but it is gone and I can't try it.

Yes, I could hear them pretty strong, so it looks like it is in the SL-1

No I have their cable, it worked with the PROIII and the G5.  It is pretty new.

Thanks for all your help.  I'll let  you know how well it works when 
I get it back.
